Bleeding the steering system
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When topping up or filling in Pentosin, make sure that Pentosin does not come into contact with the coolant hoses! In order to avoid overfilling and thus overflowing, observe the specifications in CHECKING PENTOSIN CHF 11 S HYDRAULIC FLUID IN THE POWER-STEERING SYSTEM
. If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY! Replace visibly swollen coolant hoses!
- To fill the whole system after the installation of new steering components or lines or after a substantial loss of hydraulic fluid, briefly start the engine a few times and, when it fires, switch it off again immediately. This procedure causes the fluid level in the reservoir to fall rapidly, so constantly add Pentosin CHF 11 S. The reservoir must not be sucked dry.
- If the fluid level in the reservoir does not fall any further when the engine is briefly turned over, start the engine and let it to run at idling speed.
- Rapidly turn the steering wheel from stop to stop several times so that the air can escape from the cylinders. At the end positions of the piston, do not pull the steering wheel with more force than is necessary in order to turn the steering (to prevent unnecessary build-up of pressure).
- Observe fluid level during this procedure. If it continues to fall, add fluid until the level in the reservoir remains constant and no more air bubbles rise in the reservoir when the steering wheel is turned.
- Correct the fluid level with the engine at idling speed - without operating the steering.
